DEVICE FOR WAXING- YARN.

Specification of Letters Patent.

Patented June 7, 1910.

Application filed. June 16, 1909. Serial No. 502,424.

To all whom it may concern:

Be it known that I, NATHAN E. KAHN, of IVoodbine, in the county of CapeMay and State of New Jersey, have invented a certain new and usefulDevice for WVaxing Yarn, whereof the following is a specification,reference being had to the accompanying drawings.

Prior devices having for their end the waxing of yarn, have usuallyemployed a receptacle loosely containing a number of pieces of wax, andhave passed the thread through this receptacle in such a way that itcomes more or less in contact with the edges of the broken pieces of waxtherein. This method is objectionable because of the uneven consumptionof the wax, and the consequent unevenness of the waxing of the thread.Further it admits of no means for regulating the amount of wax to beimparted to the thread. It has also beenproposed to wax yarn by passingit through a receptacle containing the wax in liquid or semi-liquidcondition, but this wastes wax, because of its absorption into the bodyof the yarn, and also involves elaborate mechanism.

I am also aware of the device patented to Gr. F. Grosser, in AustrianPatent No. 8910, issued April 25th, 1901, in which a yarn is caused topass between the shoulder of aroller and a ring of wax spring-pressedthereupon, the friction of the yarn being relied upon to impart rotationto the roller. This is objectionable because if the roller ceases torotate, the yarn cuts a groove in the wax, which prevents its furtherrotation, and soon limits the usefulness of the device. Furthermore, inthe Grosser device, the yarn is pressed against the wax, by the shoulderof the roller, and thereby subjected to undue friction, while in mydevice, the yarn has no pressure upon the wax other than its travelingtension.-

My present invention aims through a simple contrivance, to avoid theClliIlCLlltlGS of both these prior methods, and supplies a device inwhich both the solid piece of wax and the yarn to be waxed, arepositively supported in relation to each other during the waxingprocess, and such relative motion imparted to them as to cause thethread to be waxed to the desired degree only.

The device therefore consists of means for firmly supporting thetraveling yarn, as for example, on its way from the creels to the cop,in which connection the speed with which it passes through the waxingdevice may be regulated as desired; and means for positively supportingand rotating a piece of wax and maintaining it in positive contact withthe yarn as it travels through the support. In connection with thismeans I combine means for accurately adjusting the relation of the waxto the yarn, and means for maintaining the wax in constant rotationwhile the yarn passes over its axis of rotation.

When I speak in the specification and claims of positively rotating thepiece of wax, I refer to rotation imparted to the wax, by means otherthan the frictional contact of the yarn as it passes over it. Thislatter method of rotating the wax is objectionable because in so far asthe wax and the yarn move together, is the waxing eflect diminished.

In the accompanying drawings, Figure I, is a diagrammatic view of adevice embodying my invention. Fig. II, is a front elevation of the yarnwaxer. Fig. III, is a longitudinal sectional view of the same taken onthe line III, III, in Fig. II. Fig. IV, is a plan view of the device.

In the said figures, 1, designates a hollow cylindrical supporting bodyhaving lugs 2, by which it is secured to a suitable plate or table 8, asshown in Fig. I. The ends of the cylinder 1, are provided with ballbearings a, and 5, within which rotates a vertical spindle 6, carryingat its lower end a grooved pulley 7. The bearing 1, operates as a thrustbearing to vertically support the spindle by means of the bearing collar60, fast upon the spindle.

A split cup 10, is set upon the upper end of spindle 6, and is adaptedto receive a cylindrical cake of wax 11. This cup is split at 13, wherelugs 15, are provided connected by a screw 16, whereby the cylindricalcake of wax may be clamped in place with the required degree ofprojection above the edge of the cup. A spring 12, at the bottom of thecup facilitates the adjustment of the cake at the proper height whenfrom time to time the screw 16, is loosened for this purpose.

An overhanging plate 20, is provided with a circular aperture 21, whichis concentric with the axis of the spindle 6, and is slightly larger indiameter than the wax cake 11. The said plate 20, extends laterally froman arm 22, which is adjustably secured to the back of the cylinder 1, bymeans of a thumb screw 23. The said screw 23, passes through anelongated slot 25, in

the lower portion of the arm 22, whereby the latter is renderedadjustable vertically with respect to the cylinder 1. At its outer edgesplate 20, supports a pair of parallel cylindrical glass pins 26, and 27,which are respectively received in sockets 28, and 29, which only partlysurround their pins thereby exposing them at the top as clearly shown inFig. II. A second bracket 30, is adjustably secured to the back of arm22, by means of a thumb screw 31, which passes through a slot 32, in thesaid bracket 30, and is threaded into the arm 22, thus permittingrelative vertical adjustment between the two. Bracket 30, supports twolugs 34, and 35, which project laterally therefrom and carry porcelainfingers 36, and 37, respectively, which are located in line and pairedwith the glass pins 26, and 27, on'plate 20. The thread 38, passesvbetween these glass and porcelain pins, and is further guided over thecenter of the aperture 21, in plate 20, by pins 39, and 40, which areset in pairs in the plate 20, in proximity to the glass guides 26, and27.

It will be observed that the porcelain and glass fingers which have beenreferred to as coiiperating with the pins 39, and 4:0, operate not onlyas guides to position the yarn, but are also useful as imparting anadjustable tension to the same. Furthermore, by accurately adjusting thefingers in relation to the thickness of the yarn which is beingemployed, said fingers further operate as knot-catchers, causing theyarn to break in preference to permitting a knot or tangle in the yarnto pass between the fingers. The use of fingers and rods of vitreousmaterial is desirable, not only because of the clean handling of adelicate yarn, but from the fact that the yarn does not cut grooves atthe oints of contact, as is the case where meta parts are used.

As seen in Fig. I, athread bobbin 50, is carried on a spindle 51, whichis mounted for rotation in a plate 52. The said spindle 51, carries atits lower end a sheave 53, which is driven by means of a belt 54, from apulley 55, secured on a driving shaft 56.

Belt 54:, also imparts motion to the spindle 6, by means of its contactwith the pulley 7.

It is obvious that other means of imparting rotation to the spindle maybe employed, but that which I have described has the" advantage ofdefinitely relating the speed of rotation of the spindle to the speed ofthe thread bobbin. r

.The operation ofthe device is as follows :-The'constant rotation of thebobbin 50, causes the thread 38, to be drawn from the skein 57, whichmaybe supported upon suitable rollers 58, and 59, as seen in Fig. I. Therotating wax is adjusted from time to time, as it wears away,so that itsupper surface is held against the traversing thread, which is guidedover the center of the" aperture 21, in plate 20, by means of the pins39, and 40, and held in place by means of the co-action of the fingers36, and 37, with their respective glass fellows 26, and 27, ashereinbefore explained. As the upper surface of. the wax gradually wearsaway through its contact with the thread, the proper adjustment betweenthe two is constantly maintained by adjusting from time to timeeither'the height of the wax cylinder in its cup, or the verticalposition of the supporting means for the thread by manipulation of thethumb screw 23. A still more delicate adjustment is secured by varyingthe vertical position of the fingers 36, through manipulation of thethumb screw 31, and by virtue of these differing adjustments it ispossible to regulate with extreme nicety, the precise amount of waximparted to the yarn. Of course, an

additional regulation of the same maybe secured, if desired, by varyingthe rate of speed at which the yarn travels, and also the rate of speedat which the yarn cup is rotated.

By maintaining the wax cylinder in constant rotation by a positivedrive, I'secure an even wear at its upper surface, and by placing theaxis ofthe rotating waxed cylinder at right angles to the path of thetravel of the yarn, and by causing the yarn to pass over the center ofrotation, I obtain a frictional contact of the wax with the yarn in bothdirections, that is to say, both with and against the natural twist ofthe yarn, which I find to be a very effective arrangement for carryingout the end in view.

While I have shown a cup within which the wax cylinder may be clamped,it must be understood that other means of mounting the wax upon therotating spindle may be employed; When I speak of the employment of wax,I mean to include all analo-v gous waxy substances, which may beemployed to finish the surface of yarns.

It will be observed that the device as I have shown it, in the drawing,is capable of much variation, without departing from the spirit of myinvention, which essentially aims to afford positive rotation'to a piecewhich said blockof wax is set; means for rotating said holder; and meansfor leading yarn across the axis of rotation of the block of wax and incontact therewith.

2. In a yarn waxing device, the combination of means for guiding atraveling yarn with means for positively supporting and means forpositively rotating a single piece of waxy substance in such relation tothe yarn that the yarn is caused to travel across and in contact withsaid rotating piece without pressure thereon other than its travelingtension.

3. In a yarn waxing device, the combination of a cylindrical cup; meansfor rotating said cup; means for clamping within the cup a cylindricalpiece of wax with the eX- posure of one of its ends; and means forcausing yarn to pass over the axis of rotation of the wax and in contactwith its ex- ,posed rotating surface.

nation of vertical yarn guiding fingers in pairs; horizontal yarnguiding fingers also in pairs one horizontal pair being correlated toone vertical pair; and means for supporting a piece of wax between saidcorrelated pairs.

5. In a yarn waxing device, a yarn guide comprising two pairs ofhorizontal fingers; means for permitting adjustment of the verticalrelation between the fingers, and means for pressing a waxy substanceagainst the yarn as it passes from one pair of fingers to the other.

In testimony whereof, I have hereunto signed my name, at Philadelphia,Pennsylvania, this seventh day of June, 1909.
